XC6701DA52PR-G Equivalent & Substitute Parts

Part Overview

The XC6701DA52PR-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a positive fixed output of 10.5V at 150mA with a maximum input voltage of 28V and dropout voltage of 0.85V @ 100mA. The regulator includes over-current and over-temperature protection features and operates across the temperature range of -40°C to 85°C. Surface mount packaging in SOT-89 (TO-243AA) format enables integration into compact circuit designs. Identification of equivalent substitute parts becomes necessary when the primary part number is unavailable from inventory or when design flexibility is required while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Both the XC6701DA52PR-G and XC6216DA52PR-G are active products from Torex Semiconductor Ltd with full ROHS3 compliance and REACH unaffected status. Selection between these devices is based on application-specific requirements within the provided parameter set.

The XC6701DA52PR-G exhibits a quiescent current of 115 µA and PSRR of 50dB (1kHz), making it suitable for applications where power supply rejection ratio performance is prioritized.

The XC6216DA52PR-G features a significantly lower quiescent current of 9 µA and PSRR of 30dB (1kHz), making it suitable for battery-powered or low-power standby applications where quiescent current minimization is critical.

Both devices maintain identical electrical performance in terms of output voltage, output current, input voltage limits, dropout voltage, operating temperature range, and protection features. The choice between these parts depends on whether PSRR performance or quiescent current efficiency is the determining factor for the application.

Frequently Asked Questions (FAQ)

Q: Can the XC6216DA52PR-G directly replace the XC6701DA52PR-G in existing designs?

A: Yes. Both devices share identical output voltage (10.5V), output current (150mA), maximum input voltage (28V), dropout voltage (0.85V @ 100mA), operating temperature range (-40°C ~ 85°C), and SOT-89 package configuration. Direct pin-compatible substitution is supported.

Q: What is the primary difference between these two regulators?

A: The XC6216DA52PR-G has a lower quiescent current (9 µA versus 115 µA) and lower PSRR (30dB versus 50dB at 1kHz). Applications requiring minimal standby power consumption benefit from the XC6216DA52PR-G, while applications requiring superior noise rejection benefit from the XC6701DA52PR-G.

Q: Are both parts available in the same package?

A: Yes. Both the XC6701DA52PR-G and XC6216DA52PR-G are supplied in SOT-89 package (TO-243AA) with surface mount configuration, enabling identical PCB layout and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant, REACH unaffected, and maintain active product status from Torex Semiconductor Ltd.

Q: Which part should be selected for a low-power battery application?

A: The XC6216DA52PR-G is the appropriate selection for battery-powered applications due to its significantly lower quiescent current of 9 µA, which reduces overall system power consumption during standby or low-activity periods.

Q: Which part should be selected for noise-sensitive applications?

A: The XC6701DA52PR-G is the appropriate selection for applications requiring superior power supply rejection, offering 50dB PSRR at 1kHz compared to 30dB for the XC6216DA52PR-G.
